Toxic effects of both zinc and copper have been demonstrated in germmalings of Marchantia polymorpha L. and in germinating spores of Funaria hygrometrica Hedw. Copper was found to be more toxic than zinc in both species. Copper levels above 8 ppm resulted in cessation of protonemal growth and inhibition of spore germination in Funaria, and, much reduced growth of gemmalings in Marchantia. Zinc had the greatest effects on Funaria spores, and showed relatively little effect on Marchantia gemmalings. Many distinct morphological changes were observed in both bryophytes in response to Cu and Zn. Results are discussed in terms of possible uptake processes and in terms of environmental considerations. 10 references, 3 tables.
